The August 2016 update rollup includes some new improvements and fixes for the Windows 8.1 and Windows Server 2012 R2 platforms. We recommend that you apply this update rollup as part of your regular maintenance routines. Before you install this update, see the Prerequisites and the Restart requirement sections.
After you apply this update on a Remote Desktop Session (RDS) host, some new users cannot connect to an RDP session. Instead, those users see a black screen, and they are eventually disconnected. This issue occurs at unspecified intervals.
During virtual channel management, a deadlock condition occurs that prevents the RDS service from accepting new connections.
Because the RDS service is deadlocked, it cannot be restart or stopped. However, you can stop the relevant SVCHOST.EXE process in Task Manager, and manually start the RDS service to recover. When you do this, all existing users are disconnected and have to reconnect, but new users can now log on. Notice that Group Policy settings can dictate which existing sessions are closed when TermService is stopped. However, the default behavior is for users to remain logged on.
To find the RDS svchost server, follow these steps:
Start Task Manager.
On the Services tab, search on TermService.
Right-click the TermService entry, and then click Go To Details.
Note This highlights the svchost.exe entry on the Details tab.
Right-click svchost.exe, and then click End Task.
